Immersed T17 has high chip temperature

[JustaVirus]

Hello,
I could not wrap my head around how weird this is.
I have an immersion setup sized for 6,000Watts. I got an S9 to test things out and was able to hash at 16T drawing 1.4kW with chip temperature 65-68C. Never exceeding 70C.

I felt confident enough with my setup to get a T17 42t, with Braiins installed, it's currently sitting at 1.9kw with chip temperature in late 80C.

I don't understand how a 1.4kw S9 is 65C and a 500W increase in a T17 shoots chip temperature to almost 90C!

Ambient temp is 30C, fluid inlet temp is 45C.

Here is an image showing both settings for S9 and T17:

Here's my setup https://imgur.com/a/LFZIk8E

Could it be something about T17 sensors? My setup is oversized for this kind of power consumption!

It's not just the extra 500w, the number of chips on both gears are different, the chips themselves are different, and the way they attach the heatsinks on each of these models is totally different, you can only make this comparison between two S9s running at different hashrate.

But to be honest with you, I think there is something wrong with your setup, I mean even the 68C on S9 seems too high for immersion cooling, maybe it's the 30c temp outside that is causing this, you are going to need a bigger radiator and a larger pump.

Also, keep in mind that the T17 runs a bit hot by default, also the heatsinks are "loosely" attached and depending on what type of liquid you are using, the heatsinks might just come off at any second, with that in mind, 90C isn't the end of the world, your board temps show 51c, the max is  75c, this gear will die soon anyway, so I wouldn't even bother, just mine on.

Hi Mike, Thanks for your valuable input.
I too wasn't happy with S9 readings. I invested alot in this setup. The radiator is a 24x24" wood stove heat exchanger that many miners use to operate two S19s (rated for 6,000W), hooked up to a 3,000 CFM ventilation fan.I installed the radiator and the fan to an A/C hole to push hot air out and keep the room cool. The pump is also a March MDX that I've got after miners have recommended it. The tank is designed for S1X/T1X models with two chambers and a flowplate.

This T17 is the upgraded version (reinforced), I got it from China for $1,000. They have sent me a confirmation video showing the machine running and it was giving 42T with max temp 80C on air. That's what's triggering me. It worked fine on Air but not on immersion ( I couldn't even get it to 35T by immersion)

I don't know what's wrong with my setup, I've put serious money into this setup and spent 6 months building simple setups before I got to this stage, and unfortunately, the result is not exciting.

Here's my setup https://imgur.com/a/LFZIk8E, if you're interested to give your two cents.

I have noticed in the past when comparing Brains, Vnish, and stock firmware all running fixed frequency and identical conditions that Brains reports temperatures close to 10degC higher than stock or Vnish on the 17 series miners. Also, stock firmware on the T17 has a temperature target of 80 deg C, so if Brains is telling you 90, you are probably pretty much right on target.

Hello,
Are you talking about chip or board temperatures?

Hello,
Are you talking about chip or board temperatures?

Chip temperatures. I believe the board temperatures are accurate. I don't know for sure what the cause is, but I believe it has to do with the calibration of the external sense input of the TMP451 used on these boards. The external sense input is used to read the temperature of a sensor integrated into the ASIC, and needs correct calibration settings to get accurate results. The internal sensor on the TMP451 that is used to get the  "board" temperature is calibrated at the factory so it doesn't need any additional setup by the firmware.

What mikeywith mentioned is also true though. You may need different flow rates because of the different power density. A s9 running at 1400W is using only ~7.5W per chip. A T17 at 1900W is using ~21W/chip.

Makes alot of sense. What Mikey said is also concerning to me. Before I even get a T17, S9 running with temp 65C is alot and is not what an immersion system gives. You said 80C is right on the target considering Braiins exaggeration, but the gear is immersed, I should not be on target but much lower. I'll look through my system and see what I can improve, I know for sure that everything I use is high-material, could be flow-related

I'm doing 40T on my T17 with temps in mid 80s, since this reading is not accurate on Braiins, do you recommend I rise the dangerous temperature (92C) to avoid auto-shutdown? it's getting there.

Ha... at your own risk! I'm only giving you the info I observed in the past, and I didn't look into it further to get any definitive answers. I'd suggest doing your own experiment to verify what I saw. You can run stock firmware immersed if you have some fan spoofers. If you run stock in the same setup and the temps come out to be 10degC lower, then make your own conclusions...

The chips were designed to be run hot, the temperature delta to ambient is needed to move all that heat with air cooling. So you can actually run into some problems if you run too cold, timing on the ASIC design is very complicated and is temperature-dependent. So if they designed the chip for say 70degC to 90degC range, it may not meet timing requirements at 65degC for a given frequency and voltage.

I'm sure there's a sweet spot that would be below 80degC, but you'd need to experiment on that to find out. My point about the 80deg target on factory firmware is only that Bitmain seems to think that their chips are happy at that temperature.

Got it, and I was glad when you said Braiins temp readings differ because that is what I have observed while I was playing with different firmware on my S9. I did some testing and was able to determine that Braiins reads chip temperature 5-6C higher than other fws. (It read 59 in asic.io and 65 in braiins)

I'll try out different firmware and see what happens.

Try Awseomeminer firmware it's vnish firmware with added features, using their version you get to use their monitoring software for free, which I think is very useful for your set up.

What I would do is set a high profile, something 20% below the PSU's limit, and then use the monitoring software to play with the mining profile based on the temps, here an example.

If max chip temp is < 85 ( keep 52th profile)
if max chip is > 85 , ( change to 50th profile)
if current profile is 50th and chip temp is >85 - (change to 48th profile)
if mining uptime is > 2 hours and temp is below 75c and profile is 48th (change to 50th)

These are some of the many things you can do with Awseomeminer firmware, you get also get it to send you emails or telegram notifications for when something happens, the initial tuning for each profile can take a while, but when it's done once, it's done for good and switching from one profile to another will take only a few seconds, this way you can run your miner at lower hashrate during noon when it's hot, and higher when it temps cool off a bit at night.

Thank you both for helping me with this. It turns out it was true, Braiins exaggerates chip temperatures very much. From 78-80C with 1.5kw on Braiins to 60-66C with 1.4kw on ASIC.to. It is currently autotuning and things look promising. My conclusion is that immersed T17 does not do well on Braiins as it reaches 92C and autoshuts down when in fact it is within cool range.

I would have tried Awesomefirmware as it does sound awesome, but I'm already half a day into tunning with ASIC.to.

Thanks again.

I'll try out different firmware and see what happens.

the initial tuning for each profile can take a while, but when it's done once, it's done for good

How long exactly? I'm on ASIC.to and it's been tuning for almost 30 hours now. is that normal?

I can't tell for sure without seeing the tuning log, you can find them in Miner configuration > mining profiles > at the bottom of the page, copy and paste them here, please use the code tag when doing so, without it will be messy and hard to read.

Thanks!

If a hashboard errors-out for any reason during the tuning cycle, I think the Vnish firmware restarts the tuning process from the beginning. So if you have a board that occasionally has issues, it can end up tuning forever.

Your log shows some temperature sensor errors on chain 0, so my guess is that board is your problem. You might be better off trying to manually tune it from the "chip frequencies" tab.

And the log mikeywith asked for is different than the one you posted. The tuning log is not the "miner log", it is in the spot he indicated in his reply:

I can't tell for sure without seeing the tuning log, you can find them in Miner configuration > mining profiles > at the bottom of the page, copy and paste them here, please use the code tag when doing so, without it will be messy and hard to read.

hello. Yes, I've seen that too. Sorry here's the log asked:

Ok, so what the tuner is telling you is that chain 1 and 2 were tuned successfully but then chain 0 had an issue with at least 1 chip, and thus it's trying to reduce the frequency of that hash board to get to a stable point, that also perfectly matches what wndsnb mentioned about one of your hash board showing a temp sensor error in the kernel log you posted earlier.

Eventually, the tuner might get it to a stable stage, but that could take very long and thus you are better off manually setting the frequency, use 600MHz on the two good boards and start with the lowest frequency on the bad board, and then slowly increase it until it becomes stable, keep in mind that sometimes even with the lowest frequency the hash board won't hash well which means you will need to unplug so that it does not affect the other two hash boards.

On a side but related note, the two working boards seem to do very well with a frequency of 600MHz, which means you could probably increase it, that gives you more hashrate and of course more heat, so you need to find that perfect spot.

Hi Mike. Thanks for the time spent debugging my log. Yes, I did exactly that and sat the freq to 690 and volt to 16.3. It has been running smoothly for a day hashing away at 38T and drawing 2kw. More details here:https://imgur.com/a/gynUI5j.

 I have two red chips on chain 0. The moment I play around with them to get them to at least an orange, I keep getting the same error as the tuning. I decided to let them be. Are you happy with these numbers? Thanks again.

Gave you merits for reporting back, most folks don't bother after getting their issues fixed.

38TH and even 42TH is easily doable with air cooling alone even in relatively warm places, or at least that was my own "short-lived" experience with these piece of junk hardware, I am sure you can push a lot higher given your immersion cooling, but that will also increase the likely hood of gear damage, so I'd say just focus on temps, I personally think 80c is good 85c is where it start thinking about reducing my hashrate or otherwise increase the cooling if possible.

You can also attempt to lower the voltage, lowering the voltage while keeping the same frequency might result in lower temps with the same hashrate, the only issue with this model is that you can't have different voltages on different boards, so chain 1 might do ok with a lower voltage, but then chain 2 or 0 will start acting weird, it will take a lot of trial and error to get your gear's optimal settings.

But if you are a lazy old man like me, then be happy with the readings and get some rest.
